@exislander I was struggling along with the swelling in my right leg until I saw a lymphedema specialist who scheduled some tests to diagnose my condition and come up with a treatment plan. I'm really glad that I was able to go to Mayo Clinic Rochester to help me figure out what was going on. Among the tests I had done was a lymphoscintigram which checks your lymph system for blockages (In my non medical opinion☺). Mayo Clinic has some information here on Lymphedema:

I’m not sure if it is an option for you but if it is, the Mayo Clinic is very good at diagnosing health issues that are difficult to diagnose. If you would like to seek help from Mayo Clinic, you can contact one of their appointment offices. The contact information for Minnesota, Arizona and Florida can be found here:

I can relate to your wanting to get it over and stop the leaking but I would also want to know if you plug the leak between the toes is that going to cause a problem in a different area of the body.

Hoping you find some answers soon...
